Can you tell me more about the incident?
Staff have been told that a road vehicle has struck a railway bridge in this area.
This means that trains have been stopped on all lines over the bridge, so your train won't be able to travel on this route at the moment. Network Rail will be sending engineers as quickly as possible to check the bridge for any damage, and if it's safe to do so, the route will be reopened.
